I've been indoor gardening for sometime now and have encountered a bug that seems to primarily reside in the hydroton that I use. The pest looks like a tiny beetle, grayish brown, with six legs. They also seem to shed exoskeletons leaving a "peppery" mess all over the floor of my work space. I have noticed decreases in plant productivity (ie growth and harvest) and have found one product that seems to work fairly well called serenade. I would still like to have some light shed on this situation by figuring out what kind of pest I am up against. If anyone has a clue, your help would be of great assistance
